Thoraco-pulmonary mechanical perturbations accompanying thoracic load carriage

Conference Paper


Abstract

  • Mechanical perturbations to either the lung tissue or the chest wall can have deleterious effects upon

    thoraco-pulmonary mechanics, thereby modifying the work of breathing and possibly leading to respiratorymuscle

    fatigue. Thoracic loading, which is the most common form of ambulatory load carriage, is one example

    whereby an increase in the overall physiological strain is accompanied by modified, and sometimes impeded

    ventilation. However, the combined effects of the restrictive and inertial forces accompanying thoracic loading

    on the elastic properties of the entire respiratory system have not previously been evaluated. Therefore, we

    assessed the impact of thoracic loads on the static compliance of the lung tissue (Cst(l)), the chest wall (Cst(w))

    and the total respiratory system (Cst(rs)), by varying both the size and distribution of loads around the chest wall.
